Groundwater and Well Contamination

Approximately 23% of Connecticut's population relies on private wells as their source of drinking water.  A clean source of drinking water is critical to your health. Private well owners are responsible for the quality of their own drinking water.  The Department of Public Health has a variety of programs and resources available to help Connecticut residents understand private well water issues.
